(Granted under the act of `March 3, 1883, as

amended April 30, 1928;.370 G. 757) 'I'he invention describedherein, ifpatented,` may be manufactured and used byor `for the Government forgovernmental purposes without the payment of any royalty thereon.

This invention relates to ski..poles or skiing equipment and moreparticularly tothe provision of an improved snow ring or wheel.

An object of this invention isto provide a ski polehaving a snow ring orWheel which can be readily attached or'removed.

Another object of this inventionzis to provide a snow ring or `wheelthat is light in weight, that will not become water-soaked and freeze orbecome brittle.

A further object of this invention is` to provide a snow ring or wheelthat is simple `in construc- `drawing forming part of this applicationandin which similar characters and references indicate identical partsthereof and inwhich:

Fig. 1 is a side elevation of the embodiment of the invention. y

Fig. 2 is a top plan view of the snow ring or wheel. 1

4Fig. 3 is a sectional view of the same on line `Fig.` 4 is atop planview of a modified form of Fig. 5is a sectional view ofthe `same on line5--5 of Fig. 4.`

Reference now being had to the drawing by numeral, I0 indicates the skipole, which consists of ashaft or rod II, snow ring or wheel I2 and handgrip I3, having a strap I4 secured thereto.

The ring I2 in general as shown inFigs. 1 and` 2, comprises a. ring I5of `tubular metallic forf` `mation, which, as shown, is circular incrosssection, although it might be any` shape desired.

f z Itis an important feature of `tl'iisinvention thatthe spokes I6 bemade of rubber vulcanized on a cotton carcass I1. One advantage ofconstruction is that the entire wheel may be molded `from the spirit ofthe invention or $0` as `a unit."` Rubberis aparticularly desirabley ma`terial, since it can be easily moldedand is highly resistant to waterand'wean The resiliency of the `rubber spokesjof the 4wheel tend tofreeit from` snowandany ice incrustations that might form thereon and`sincerubber isimpervions to water the ring or wheel will"not becomewatersoaked and freeze, `thereby becoming brittle, and cracking orbreaking under strain. Therubber snow rings now in use are not strong ordependable and this particularI ringvha's overcome these old drawbacks.

Asshown at I8` in Fig. 2 the spokesfl areA molded `directlyto and aroundthe ring `I5 while in Fig. 4 the ring I5 is provided with atsurfaces andspoke anchors 20 to receive the spokes I6.` This form gives somewhatgreater 4flexibility but otherwise di'ers very The spokes I6 areprovided with hub portions 22 having an opening 23` therein to receivethe shaft II.

` The structurethus described is strongerthan a Y plain rubber ring andis practically indestructible.

It is to be understood that the illustrations shown are given by way` ofillustration only and ont byway of limitation, and that changes andmodifications may be made Without departing fall beyond the scope of theappended claims.

Having thus described `the invention, what is claimed as new and desiredto secure by Patent is:

1. A` ski `pole having a snow ring comprising a tubular ring', rubberspokes having a cotton carcass molded integrally with said ring, saidspokes having a hub portion adapted to `receive the `ski pole, saidcotton carcass having a U-shaped formation with bothk ends terminatingwithin said hub portion. I

` 2, A ski pole wheel comprising a tubular ring, rubber spokes molded'on a cotton` carcass `integrally Withsaid ring, said spokes having ahub portion adapted to receive a ski pole, said cotton carcass having aU-shaped formation, the ends thereof `terminating in the hub portion ofsaid ring, said cotton carcass also adapted to contact said ring toprevent wear on the interor offsaid spokes.
